Abstract

See full text

The invention is directed to a urea plant with a high pressure synthesis section and a recovery section. The high pressure synthesis section comprises a reactor, a stripper and a condenser, wherein the reactor operates at a higher pressure than the stripper and the condenser. The plant further includes a compression unit between the condenser and the reactor. The compression unit utilizes mechanical energy recovered from a decompression unit positioned downstream of the stripper and upstream of the recovery section.
